Apparatus and method for fixing a plurality of glass substrates to a box

The present application claims the priority of the Korean Patent Application No. 10-2016-0069454, filed on Jun. 3, 2016, the content of which is hereby incorporated by The case.

The present invention relates to an apparatus and method for securing a plurality of glass substrates arranged in a stack to a box, and more particularly to a fixing device capable of reducing the pressure applied to both side portions of the stack of glass substrates and applying to the stack The difference between the pressures of the central portion of the glass substrate.

Glass substrates are used in a variety of applications, such as display devices, buildings, vehicles, solar cells, and the like. The glass substrate is processed, for example, by melting the raw material of the glass and shaping the molten material into the shape of the substrate. When a conventional method is required to transport a processed glass substrate, a plurality of glass substrates are packaged together into one glass substrate box to reduce the cost of shipping. For example, a stack of glass substrates is carried on a case and packaged using a fixing bar that extends across the front surface of the first glass substrate in the lateral direction (width direction). Both ends of the fixing rod are connected to the frame of the box using a cam type fixing rod. With this configuration, a large amount of pressure can be applied to both side portions of the stack, and the central portion of the stack is bent because the fixing bar is lifted from the stack of glass substrates at the central portion of the stack. Therefore, the fixing force applied to the central portion of the laminated glass substrate is reduced. When the stacked glass substrates are transported in this orientation, the glass substrates collide with each other during transportation due to movement. This can cause defects such as cracks or cracks in the glass substrate in the stack.

Various aspects of the present invention provide a case on which a glass substrate is carried, which can increase the total force applied to a stack of glass substrates to secure the stack of glass substrates in position, particularly to the stack of glass A force of the central portion of the substrate, thereby reducing the difference between the pressure applied to the both side portions of the stacked glass substrate and the pressure applied to the central portion of the stacked glass substrate.

According to an embodiment of the present disclosure, the case may include: a frame and at least one binding unit. The frame can include a base and a back member, wherein a stack of glass substrates is carried on the base adjacent the back member, the width and height of the stack intersecting each other perpendicularly. The at least one binding unit may include: a restricting portion including a longitudinal portion and a central protruding portion extending across the stack in a direction of the width of the stack, the central protruding portion being orthogonal to the stack Projecting from a central portion of the longitudinal portion in a direction of the front surface; a first grip portion and a second grip portion, the first and second grip portions being aligned with the longitudinal portion of the restricting portion and fixed to the a back member of the frame; and a strap that is fastened and extends between the first and second grips such that the strap contacts the central projection, wherein the strap passes the central projection and the strap The longitudinal portion applies a force to the front surface of the stack.

In some embodiments, the bin may contain a plurality of staple units, such as at least two staple units. Therefore, the case including the at least two binding units may further include at least one connecting member that connects the restricting portions of the at least two binding units to each other.

According to the present disclosure, the central projection projecting forward from the central portion of the longitudinal portion of the restricting portion can increase the total pressure applied to a stack of glass substrates, particularly the amount of pressure applied to the central portion of the stack of glass substrates. This can reduce the difference between the pressure applied to both side portions of the stacked glass substrate and the pressure applied to the central portion of the stacked glass substrate. Therefore, the fixing force applied to the stacked glass substrate through the fixing means can be increased, and the plurality of glass substrates can be reliably packaged and transported after being loaded into the case.

Furthermore, a torque wrench can be used, for example, to adjust the extent to which the belt is wound onto the spool, so that the pressure can be accurately and evenly applied to the entire stack of glass substrates carried on the plurality of bins.

Moreover, according to the disclosure, the connecting elements connecting the restricting portions of the plurality of binding units can facilitate the operation of the fixing device.

Furthermore, the guides and side projections provided on the front portion of the central projection can prevent the straps from being disengaged during or after the fastening of the straps.

Moreover, by removing too much material, the weight of the glass substrate fixing device can be reduced, thereby facilitating transportation and increasing the workability of the fixing device.

In a further embodiment, a method of securing a glass substrate to a box is disclosed, the method comprising the steps of carrying a plurality of glass substrates on the box, the box comprising a frame, the frame including a base and a back member, A plurality of glass substrates are carried on the base adjacent to the back member to form a stack of glass substrates, the stack of glass substrates including a width and a height that intersect the height perpendicular to each other.

The at least one binding unit may include a restricting portion including a longitudinal portion and a central protrusion extending through the stack in a direction of the width of the stack, the central protrusion being on a front surface of the stack The central portion of the longitudinal portion protrudes in the orthogonal direction. The at least one binding unit may further include a first grip portion and a second grip portion, the first and second grip portions being aligned with the longitudinal portion of the restricting portion and fixed to the back member of the frame. The at least one binding unit may include a belt that is fastened and extends between the first and second grips such that the strap contacts the central projection, wherein the method may further comprise a belt to apply a force to the front surface of the stack via the restricting portion.

In some embodiments, the step of tensioning the strap can include the step of rotating the first grip to cause the strap to wrap around the first grip.

In some embodiments, the first grip portion can include a spool, the spool includes an angled head, and the step of rotating the first grip can include the step of rotating the angled head of the spool .

1 to 3 are schematic views illustrating a case in which a glass substrate fixing device is fixed to a frame on which a glass substrate is carried, in accordance with an exemplary embodiment.

As shown in FIGS. 1 to 3, the case 10 includes a frame 11 and a glass substrate fixing device 100. The box 10 is used to package components of the glass stack 20 (i.e., a stack of glass substrates) for transport. The frame 11 includes a base 11a and a back member 11b. The glass stack 20 is carried over the base 11a adjacent to the back member 11b. In some embodiments, as shown in FIGS. 1-3, the glass stack 20 can be carried on the frame 11 in an upright position. However, in a further embodiment, the glass stack 20 can be carried with an oblique orientation. In the case of a tilt bearing, the base 11a and the back member 11b will have a corresponding structure.

The front surface of the first glass substrate of the stack 20 is formed as the front surface of the stack. From the back member 11b, the glass substrates are stacked on the frame 11 in the direction of the front surface of the stack 20. In general, the width of the stack 20 is in the horizontal direction and the height of the stack 20 is in the vertical direction. As described above, when the frame is an inclined frame, the vertical direction is also inclined by an angle, which is the angle at which the frame is inclined.

The glass substrate fixing device 100 is disposed in front of the glass stack 20 and is coupled to the frame 11. In this position, the glass substrate fixing device 100 transmits the glass stack 20 by pushing the stack 20 from the front. Although the glass substrate fixture 100 is illustrated as being in close contact with the front surface of the glass stack 20 for simplicity, at least one layer (including, for example, a cushion or a plate) may be disposed between the glass stack 20 and the glass substrate fixture 100, To protect the glass stack 20 . Further, when the glass stack 20 is fixed to the case 10 using the glass substrate fixing device 100, the case 10 may be covered with a vinyl package or the like before shipping.

As shown in FIGS. 4 to 7, the glass substrate fixing device 100 that fixes and packages the glass stack 20 carried on the frame 10 includes two or more binding units 101 and one or more connecting members 130. Each of the binding units 101 includes a restricting portion 103, a first grip portion 150, a second grip portion 160, and a belt 140. The restricting portion 103 includes a longitudinal portion 110, a central protruding portion 120, and a side protruding portion 125.

The longitudinal portion 110 is an element that utilizes the pressure transmitted by the belt 140 to urge the glass stack 20 into close contact with the frame 11 by pushing the front side of the glass stack 20. The longitudinal portion 110 has the shape of a rod that extends through the glass stack 20 in the lateral direction of the glass stack 20 and in close contact with the front side of the glass stack 20. Embodiments of the present invention may include two or more longitudinal portions 110 to achieve a uniform contact or securing force on the entire surface of the glass stack 20. Advantageously, a fixture 100 having more than two longitudinal portions 110 is provided to increase the holding force over the entire surface of the glass stack 20. However, since the glass substrate fixing device 100 is transported by a worker, the excessive longitudinal portion 110 may reduce workability, such as an increase in fixing and/or loosening time. The illustrated embodiment provides two longitudinal portions 110, an upper longitudinal portion 110 and a lower longitudinal portion 110 that extend in a lateral direction and are in intimate contact with the upper and lower portions of the front surface of the glass stack 20, respectively. Further, the upper and lower longitudinal portions 110 may be configured to be parallel to each other. In some embodiments, the upper and lower longitudinal portions 110 may be interconnected by a connecting member 130, although in further embodiments, the upper and lower longitudinal portions may not be connected. Further, each central projection 120 may be disposed over a central portion of a corresponding longitudinal portion 110 to increase the pressure applied to the central portion. The hooks 111 may be disposed at both ends of the upper longitudinal portion 110. The hook 111 is used to connect the upper longitudinal portion 110 to the first grip portion 150 and the second grip portion 160. The relationship will be described in detail below.

As shown in FIGS. 5 to 8, the central protrusion 120 protrudes forward from the central portion of the corresponding one of the upper and lower longitudinal portions 110. The central projection 120 is used to lift the strap 140 from the central portion of the longitudinal portion 110, the strap 140 being coupled to the central projection 120 and the longitudinal portion 110 in a belt-like manner. When the belt 140 is lifted in this manner, the pressure applied to the central portion of the longitudinal portion 110 may increase. Likewise, the side protrusions 125 project forward from both longitudinal ends of each of the upper and lower longitudinal portions 110. Therefore, the central protrusion 120 and the side protrusion 125 allow the belt 140 of the portion extending between the central protrusion 120 and the side protrusion 125 to be spaced apart from the longitudinal portion 110. Advantageously, the amount by which the central projection 120 protrudes from the longitudinal portion 110 is greater than the amount by which the side projections 125 protrude from the longitudinal portion 110.

In general, if the belt 140 is combined with the longitudinal portion 110 that does not have the central projection 120, the pressure will concentrate on both side portions of the longitudinal portion 110. Therefore, the contact force of the central portion of the longitudinal portion 110 with the front surface of the glass stack 20 is reduced, so that the fixing force toward the central portion of the glass stack 20 is reduced. To avoid this, as in the present embodiment, the central projection 120 can be disposed on a central portion of each of the upper and lower longitudinal portions 110. This configuration can increase the pressure applied to the central portion, thereby increasing the contact force of the central portion of the longitudinal portion 110 with the glass stack 20. Further, when the central projection 120 is used to increase the pressure applied to the central portion of the glass stack 20, the difference in pressure between the side portions subjected to the pressure concentration and the central portions can be reduced or minimized. Therefore, a relatively uniform pressure can be applied to the entire surface of the glass stack 20, whereby the fixing device 100 can more stably fix the glass stack 20 to the frame 11, and more reliably package and transport the glass stack.

In some embodiments, each of the central protrusions 120 can include at least one aperture 121 that extends through the central projection 120 in a vertical direction. Since the glass substrate fixing device 100 is handled manually, the glass substrate fixing device 100 should have a minimum weight that facilitates transportation or enhances worker handling. In order to lift the belt 140 from the central portion of the longitudinal portion 110, the central portion 120 is only necessary. In addition, it will be explained below that only the height at which the belt 140 is lifted affects the increase in pressure applied to the glass stack. The increase in length in the contact of the strip 140 with the central projection 120 does not have a significant effect on the increment of pressure applied to the glass stack. Therefore, in order to reduce the weight of the glass substrate fixing device 100, the central projection 120 can be designed to have a minimum size that must be able to withstand the pressure applied by the belt 140, and must be adapted to the hole 121, which represents a central protrusion. In the case where the supporting force of the portion 120 is not reduced to a range, the non-essential material may have the largest size.

When the connecting element 130 is in effect, the upper and lower longitudinal portions 110 are joined, whereby the upper and lower longitudinal portions 110 remain parallel to each other. For example, the connecting members 130 may be disposed in a pair and extend in the vertical direction of both sides of the central protrusion 120. Furthermore, the two longitudinal ends of the connecting elements 130 can be connected to the upper and lower longitudinal portions 110. The connection portion 130 may be coupled to the front side of the longitudinal portion 110 by applying pressure to the glass stack 20 using the longitudinal portion 110. The connecting element 130 can be used to keep the upper and lower longitudinal portions 110 spaced apart from each other by a predetermined distance. Furthermore, the connecting element 130 can act as a handle to allow a worker to grasp the pair of longitudinal portions 110 simultaneously and to facilitate finding the position of the pair of longitudinal portions 110 provided on the front side of the glass stack 20. Further, as will be explained below, the connecting member 130 allows the support member and the hook to be omitted from the lower binding unit. That is, the connecting member 130 is not required, and the support member and the hook are available for the upper binding unit and the lower binding unit.

As shown in FIGS. 1-3, the belt 140 is an element that applies pressure to the upper and lower longitudinal portions 110 such that the longitudinal portion 110 is in intimate contact with the front side of the glass stack 20. The strap 140 can have a curved shape, such as a strap. Each of the straps 140 is coupled to the front side of the longitudinal portion 110 via the central projection 120 and the side projections 125 such that the pressure applied to the longitudinal portion 110 is adjustable. When the belt 140 is disposed in the above-described belt-like manner, the belt 140 is lifted by the central projection 120 such that the belt 140 comes into contact with the partial longitudinal portion 110 via the central projection 120 and the side projections 125. That is, the belt 140 will come into contact with the central projection 120 and the side projections 125, but will not contact the other portions of the longitudinal portion 110.

FIG. 16 is a graph illustrating the analysis result of Comparative Example 1. In Comparative Example 1, both ends of the fixing rod having no protruding portion were fixed to the frame by a cam type fixing lever. In the case of Comparative Example 1, the maximum value of the measured stress was 137.4 MPa at both ends of the fixed rod and 0 MPa at the central portion. It can be understood that the stress in Comparative Example 1 is concentrated on both ends of the fixed rod, and substantially no stress is applied to the central portion.

17 is a graph illustrating the analysis result of Comparative Example 2. Comparative Example 2 is different from Comparative Example 1 in that the shape of the regulating portion is changed to a triangular shape from above. It can be understood that in the case of Comparative Example 2, the measured stress and the maximum value of the contact pressure are at both the longitudinal end and the central portion. That is, the measured magnitude of the stress due to the pressure is 92.5 MPa in the central portion and 190.2 MPa in the both ends. The measured value of the stress at the portions of the two oblique sides of the triangle was 0.1 MPa. This means that only the central portion that protrudes at the maximum distance contributes an increment to the pressure. Further, comparing Comparative Example 2 with Comparative Example 1, it is understood that the stress at both ends in Comparative Example 2 also increases, so that the magnitude of the entire stress is increased.

Figure 18 is a chart illustrating the results of an analysis in accordance with an embodiment of the present invention. In the embodiment of the present invention, the protruding portion is formed only at both end portions of the central portion and the longitudinal portion. As in Comparative Example 2, it is understood that the stress is concentrated at the central portions of the two longitudinal ends and the longitudinal portion. In particular, the measured maximum value of the stress due to the pressure was 120.8 MPa in the central portion, 165 MPa at both ends, and the portion between the two was 0 MPa. It can be understood that, in the case of the present embodiment, the stress in the central portion is increased, and the difference in pressure between the pressure at both ends and the pressure at the central portion is reduced as compared with Comparative Example 2. When the projecting portion projecting forward, as in the embodiment of the present invention, is formed at both end portions of the central portion and the longitudinal portion, the pressure can be more preferably distributed to the central portion of the longitudinal portion, and in Comparative Example 2, the pressure is also Focus on the central part. On the other hand, with respect to the embodiment of Fig. 18, the difference in pressure between the central portion and both ends can be reduced as compared with the comparative example 2, whereby the force is transferred to the stacked glass substrate. Therefore, it can be understood that, in the present embodiment, only the restricting portion having the protruding portion at the central portion and the two end portions can uniformly distribute the pressure and reduce the weight of the fixing device.

According to the embodiment of the present invention, one end of the strap 140 can be fixed to the first grip portion 150, which will be described below. The second grip portion 160 includes a rod 163. The strap 140 extending from the first grip 150 is wrapped around and extends beyond the stem 163. The other end portion of the strap 140 extending beyond the rod 163 is positioned to overlap the strap 140 of the portion extending between the first grip 150 and the stem 163, and then the two portions of the strap are coupled by the coupling member 170 The modes are coupled to each other. That is, the coupling member 170 couples the two portions of the belt that extend from the rod 163 to each other. The coupling element 170 can be a buckle. Further, the belt 140 may be guided by a plurality of guides 180 and 185 provided at the front of the central projection 120 and forward of the side projections 125. The guides 180 and 185 define a passage along which the belt 140 is moved by forming a loop at the front of the central projection 120 and the front projection 125. When the plurality of guiding members 180 and 185 are formed on the passage of the fastened belt 140, the belt 140 can be prevented from being disengaged during or after the fastening of the belt 140, thereby enhancing the glass substrate fixing device 100. Reliability.

As described above, in order to connect the belt 140 and the pair of longitudinal portions 110 to the frame 11, the glass substrate fixing device 100 may include a first grip portion 150 and a second grip portion 160. The grips 150 and 160 can be aligned with the longitudinal portions 110.

The first grip portion 150 may be disposed on the upper and lower portions of the right wall of the frame 11. The upper and lower first grips 150 may be further disposed to have a distance equal to the distance between the upper and lower longitudinal portions 110. The first grip 150 secures the right end of the strap 140. Additionally, the first grip 150 can adjust the amount of pressure applied to the longitudinal portion 110 via the strap 140 through the pull and wrap. That is, the worker can adjust the magnitude of the pressure applied to the stack of glass substrates 20 carried on the frame 11 by manipulating the first grip portion 150.

As shown in FIGS. 9 to 12, each of the first grips 150 includes a body 151 and a bobbin 152. The body 151 is fixed to the right wall of the frame 11 and serves to support the bobbin 152 to which it is attached. The spool 152 is an element that substantially secures one of the corresponding straps 140. The spool 152 is wound to wind the corresponding belt 140 thereon so that the belt 140 is tensioned. In this regard, the spool 152 is coupled to the body 151 such that the spool 152 can rotate on its vertical axis. As shown in Figures 9-12, the spool 152 is coupled to the body 151 in a position at which the spool 152 extends through the mutually facing upper and lower horizontal bracket plates of the body 151. In particular, the upper portion of the spool 152 projects beyond the upper horizontal bracket plate of the body 151, and the remainder of the spool 152 is disposed between the mutually facing upper and lower horizontal bracket plates of the body 151. The spool 152 has a slit 152a at this portion provided between the upper portion of the body 151 and the lower horizontal bracket plate. The strap 140 passes through the slot 152a and then extends toward the longitudinal portion 110. In this case, since one end of the belt 140 must be fixed to the bobbin 152, one end of the belt 140 may be thicker than the width of the slit 152a, so that one end of the belt 140 cannot pass through the slit 152a. Alternatively, one end of the strap 140 can be secured to the bobbin 152 with a separate securing member or directly to the bobbin 152.

In accordance with an embodiment of the present invention, a torque wrench can be utilized to adjust the extent to which the strap 140 is wrapped around the spool 152 in a first direction. For example, the degree of winding of the belt 140 can be adjusted such that the maximum pressure applied to the belt 140 ranges from 200 kgf/cm ² to 500 kgf/cm ² . When the torque wrench is used in this manner, the amount of tension applied to the belt 140 can be digitally adjusted. Thereby, it is possible to apply pressure to the entire glass substrate stack carried on the plurality of frames 10 accurately and uniformly. To this end, it is advantageous to have the head of the spool 152 at an angle so that a torque wrench can be used.

Each of the first grips 150 includes a reverse prevention portion 153 to hold the belt 140 in a pressure position in which the belt 140 is tensioned to apply pressure to the projections 120 and 125 and the longitudinal portion 110. The anti-reverse portion 153 is a device that prevents the bobbin 152 from rotating in the opposite direction, and the reversing portion 153 is prevented from including the ratchet 153a and the pawl 153b. A ratchet 153a is provided on the outer circumference of the upper portion of the bobbin 152 to protrude above the upper horizontal bracket plate of the body 151. With this configuration, when the bobbin 152 is rotated, the ratchet 153a rotates together with the bobbin 152. The pawl 153b is pivotally disposed on a portion of the body 151 adjacent the ratchet 153a, and more particularly, on a horizontal bracket plate above the body 151 of the ratchet 153a. The pawl 153b is engaged with the ratchet 153a such that the pawl 153b can allow the ratchet 153a to rotate with the spool 152 in a first direction, in which the strap 140 is wound around the outer circumference of the spool 152 while preventing the ratchet 153a from being opposed Rotation (i.e., reverse) in a second direction of the first direction prevents the belt 140 from being unwound from the outer circumference of the spool 152. In this manner, the glass substrate fixing device 100 according to the embodiment of the present invention can continuously maintain the fixing force on the glass stack 20 by the reverse preventing portion 153. The ratchet mechanism allows for a predetermined increment of tension to be set.

The second grip portion 160 may be disposed on the upper and lower portions of the left wall of the frame 11. The upper and lower second grips 160 may be disposed at positions corresponding to the upper and lower first grips 150. In each of the second grips 160, the rod 163 acts as a redirecting lever, by which the strap 140 extending from the first grip unit 150 is redirected toward the first grip 150 . The rod 163 of the second grip portion 160 allows the belt 140 to be wound thereon. In particular, the rod 163 of the second grip portion 160 guides the left end of the strap 140 to be redirected toward the first grip portion 150. The left end of the belt 140 extending from the second grip portion 160 toward the first grip portion 150 is placed to overlap the belt 140 of the portion extending between the first grip portion 150 and the second grip portion 160, and then The two parts are coupled to each other by a snap-fit coupling element 170.

The upper first grip portion 150 and the upper second grip portion 160 may include support members 150a and 160a, respectively. The support members 150a and 160a are respectively disposed on the first grip portion 150 and the second grip portion 160 such that the support members 150a and 160a are rotatable in the direction of the upper longitudinal portion 110. The supports 150a and 160a are in the shape of a rod. Hooks 111 provided at both ends of the upper longitudinal portion 110 may be placed on the support members 150a, 160a. Further, the ends of the support members 150a and 160a may be bent upward to prevent the hooks 111 placed thereon from slipping off. As shown in FIG. 13, before the hooks 111 are placed on the supports 150a and 160a, the supports 150a and 160a are located in a straight cubic position (first orientation) near the side walls of the frame 11 without hindering stacking of the glass. 20 operations carried on the frame 11. The support members 150a and 160a in the first orientation are separated from the restriction portion 103, and thus the restriction portion 103 is not supported. When the glass substrate fixing device 100 is attached to the frame 11, the support members 150a and 160a are rotated by a straight cubic position as shown in FIG. 13 to a horizontal orientation (second orientation) as shown in FIGS. 14 and 15, such that the upper portion The hooks 111 of the longitudinal portion 110 can be placed on the supports 150a and 160a.

A method of connecting the glass substrate fixing device according to the present embodiment to a frame will be described below.

First, the worker grasps the connecting member 130 and then moves the set of the connecting member 130 and the restricting portion 103 such that the hook 111 of the upper longitudinal portion 110 is placed on the supporting members 150a and 160a of the first and second grip portions 150 and 160. on. Thereafter, the worker fixes one end of the strap 140 to the lower first grip portion 150, and then sequentially passes the strap 140 through the plurality of guide members 180 and 185 disposed in front of the projections 120 and 125.
